The so-called WAP gap involves the ______ of information where the two different networks meet, the WAP gateways.
Group of answer choices
A. integrity.
B. confidentiality.
C. authentication.
D. WTLS.
Answer:
B. confidentiality.
Step-by-step explanation:
WAP is an acronym for wireless application protocol and it is a standard communications protocol used for accessing, formatting and filtering of data (informations) on wireless devices such as mobile phones over the internet or mobile wireless network.
Simply stated, a wireless application protocol (WAP) is a lightweight and easy to use protocol designed and developed for devices with low computing power e.g mobile devices.
There are two (2) main standard protocols that are being used for the wireless application protocol (WAP), these are;
1. Transport Layer Security (TLS).
2. Wireless Transport Layer Security (WTLS).
The so-called WAP gap involves the confidentiality of information where the two different networks (WTLS and TLS) meet, the WAP gateways.
In wireless communications, the wireless transport layer security was an improvement on the transport layer security. However, it created a major problem of confidentiality in the translation of the two protocols in a WAP architecture.
First, the user data is encrypted with a public key of an application server and then encrypted again from the client mobile device to the WAP gateway using the wireless transport layer security (WTLS) and lastly, the transport layer security (TLS) is used from the WAP gateway to the enterprise server. The TLS translates the WTLS data by decrypting it first and then encrypting it again.
The security concerns or confidentiality issues associated with using WAP is that, all messages are seen in plain text by the WAP gateways in the translation at the TLS point, thus causing the so called WAP gap.
